Abstract
Myxomas are the most common cardiac primary tumors; however, left ventricular myxomas are extremely rare. We describe a young female patient with a giant left ventricular myxoma causing partial obstruction of the left ventricular outflow tract, who underwent successful surgical resection. Real-time three-dimensional echocardiography yielded incremental value to two-dimensional echocardiography by allowing better assess of the true size, extent, attachment, and morphology of the tumor. © 2017 Wiley Periodicals, Inc.

Abstract
Carney complex(CNC) is a rare genetic syndrome, characterized by spotty pigmentation of the skin, cardiac myxomas and multiple endocrine tumors. We present a case of asymptomatic cardiac myxoma associated with CNC. She was 49 year-old healthy woman whose son was known to have CNC. She was also diagnosed as CNC due to her family history, typical cutaneous findings and screening endocrine test. Screening ultrasound echocardiography resulted in discovering her asymptomatic left atrial myxoma of 30 mm size. Tumor was successfully resected via median sternotomy and no signs of recurrence were observed at 1 year follow up. Periodical follow up is mandatory because of its high recurrence rate.

Abstract
Cardiac myxomas are rare tumors. Esophageal adenocarcinomas are common tumors of the gastrointestinal tract. Simultaneous occurrence of these tumors has not been reported. A 52-year-old gentleman presented to our hospital with dysphagia and was diagnosed with esophageal adenocarcinoma. Routine echocardiography discovered a cardiac tumor in the left atrium. The cardiac tumor was surgically removed and biopsy confirmed a myxoma. We removed the cardiac tumor as the first step and then initiated neoadjuvant chemotherapy. It is ideal to constitute a multidisciplinary team to decide on the course of treatment in such cases.

Abstract
Renal myxoma is a very rare benign neoplasm seen almost exclusively in adults with only 16 reported cases in the literature. All of these cases have been reported in native kidneys with none being reported in a transplant kidney. We report the case of a renal myxoma in a 17-year-old boy's transplant kidney that was found as an incidental mass on ultrasonography and further evaluated with CT and PET scans. PET findings of a renal myxoma are reported here for the first time, and imaging findings from previous cases are briefly reviewed. This case report highlights the fact that adult-predominant tumors and pathology should always be a consideration in pediatric patients who receive organ transplants from adult donors.

Abstract
Myxoma is the most common tumor in the heart. A typical myxoma is relatively straightforward to diagnose. However, certain cardiac myxomas have rare features. We report three extremely rare cases of cardiac myxoma. One case involved a myxoma that originated from the annulus of the tricuspid after valvuloplasty, one case involved myxomas associated with left atrial thrombus and severe mitral stenosis, and the third case involved myxoma combined with severe calcification. All three cases were diagnosed by echocardiography and pathology. We also review clinical presentations and diagnostic characteristics of cardiac myxomas.

Abstract
Cardioembolic stroke is an uncommon phenomenon in pediatric patients. Although the heart is the usual source of the condition, cardiac myxomas are still considered to be a rare cause in children. The case is presented of a 13-year-old, right-handed Saudi boy who showed right-sided weakness for 30 h prior to hospital admission that involved the face, arm, and leg, with slurred speech. The patient had been discharged previously from a local hospital, without active management. An examination showed decreased strength on the right side, with hyperreflexia and an up-going plantar response. The work-up included magnetic resonance imaging, which demonstrated multiple bilateral acute infarcts involving mainly the left cerebellum and a small focus in the right cerebellum. Transthoracic echocardiography demonstrated a left atrial mass measuring 1.9 cm × 2.4 cm, attached to the septum. The mass was resected after anticoagulation, and histopathology confirmed a benign myxoma. This case of cardioembolic stroke was the first to be identified in a pediatric patient in Saudi Arabia, and may easily have been missed. Brain imaging and echocardiography should be performed as soon as possible in such patients in order to guide patient management.

Abstract
CASE DESCRIPTION A 15-year-old neutered female mixed-breed dog (dog 1) and an 11-year-old neutered female Labrador Retriever (dog 2) were examined because of unilateral exophthalmus, third eyelid protrusion, and periorbital swelling that failed to respond to antimicrobial treatment. CLINICAL FINDINGS Both dogs underwent ultrasonographic, CT, and MRI examination of the head. In both dogs, advanced imaging revealed a poorly defined, peripherally contrast-enhancing, mucous-filled cystic mass that radiated from the temporomandibular joint and infiltrated the periorbital tissues and retrobulbar space. Both dogs underwent surgical biopsy of the periorbital mass. A viscous, straw-colored fluid was aspirated from the retrobulbar region in both dogs. The initial histologic diagnosis for dog 1 was zygomatic sialadenitis and sialocele. However, the clinical signs recurred, and histologic examination of specimens obtained during a second surgical biopsy resulted in a diagnosis of myxoma. The histologic diagnosis was myxosarcoma for dog 2. TREATMENT AND OUTCOME In both dogs, clinical signs recurred within 2 weeks after surgery and persisted for the duration of their lives. Dog 1 received no further treatment after the second surgery and was euthanized 34 months after initial examination because of multicentric lymphoma. Dog 2 was treated with various chemotherapy agents and was euthanized 11 months after initial examination because of a dramatic increase in periocular swelling and respiratory stertor. CLINICAL RELEVANCE Temporomandibular myxomatous neoplasia can be confused with zygomatic sialocele on the basis of clinical signs but has characteristic MRI features. Representative biopsy specimens should be obtained from areas close to the temporomandibular joint to avoid misdiagnosis.

Abstract
There are two types of tumors found in the cardiac chamber. These are divided into primary intra-cardiac tumors and secondary intra-cardiac tumors. Primary intra cardiac tumors are rare and among them 29% are myxomas. Majority of them are found in the left atrium. Here, we report a case of a myxoma in the right atrium with hepatomegaly and Hepatitis B virus infection. The coexistence of all these conditions is very rare. A 52 years old patient presented with history of shortness of breath on exertion along with fever and generalized weakness for 6 months which aggravated lately for last 2 months. He was then taken for better medical care and hospitalization. On cardiac evaluation he had soft S1 and S2 over the tricuspid region on the right lower parasternal region. He had bilateral mild pitting pedal edema. On further examination, it was revealed that he had mild tender hepatomegaly with jaundice. His blood analysis for HBsAg was positive. Echocardiogram showed right atrial myxoma of 14.3cm² almost completely occupying the right atrium and even protruding into the Inferior Venacava however not fully obstructing it. The inferior vena cava size was mildly dilated (22mm). Abdominal ultrasound report showed hepatomegaly (17.6cm) with coarse hepatic parenchyma. In this report, we emphasize the rarity of myxoma in the Right Atrium, its difficult diagnosis because of the location and the atypical presentation in the echocardiograph.

Abstract
Odontogenic myxoma (OM) is a non-metastasizing neoplasm of mesenchymal origin, arising in the tooth-bearing areas of the jaws. When regarding the whole spectrum of differential diagnoses for osteolytic jaw lesions, OM constitutes a benign tumor rarely located in the maxilla. Radiographically, displacement of teeth and frequent involvement of the sinus will be found with advanced maxillary OM. The tumor can be removed by means of several techniques, ranging from conservative measures to extended surgical procedures that differ according to type of bone resection and reconstruction of the defect. This report documents 10 years of follow-up in a patient suffering from a Type IV lesion of maxillary OM; with a radiographically proven growth extending into the right maxillary sinus, the patient underwent a segmental maxillectomy. After a tumor-free period of 5 years, the alveolar ridge splitting technique (ARST) was modified to insert dental implants into the horizontally deficient alveolar ridge of the maxilla, and final rehabilitation by means of a conditionally removable prosthetic reconstruction followed. In this paper, the most striking clinical signs of OM with which the dentist should be familiar are reviewed, and we discuss the advantages of segmental maxillectomy in case of an OM, along with the possibility of using ARST, aiming at prosthetic rehabilitation by placement of dental implants in cases of moderate alveolar ridge deficiency after tumor resection.

Abstract
RATIONALE An intracardiac cystic mass is a rare type of mass found in the left atrium. The differential diagnosis of an intracardiac cystic mass includes hydatid cysts, bronchogenic cysts, intracardiac varices, and hemorrhages in some tumor types, including myxoma. PATIENT CONCERNS We present the case of a 68-year-old woman who presented with episodic dyspnea. DIAGNOSES-INTERVENTIONS-OUTCOMES Transthoracic echocardiography (TTE) revealed the presence of a left atrial mass mimicking myxoma. However, in postoperative findings, it was determined that the mass was actually a hemorrhagic cyst. Eighteen months later, the patient presented with recurrent exertional dyspnea and TTE revealed the recurrence of a left atrial mass. Computed tomography showed that the mass extended into the right atrium, inferior vena cava, and coronary sinus. After re-operation, the final histological diagnosis was determined to be an undifferentiated pleomorphic sarcoma in the left atrium. LESSONS An intracardiac hemorrhagic cyst was suspected during the operation of a benign-looking LA mass. As such, we recommend that other rare etiologies be considered and more biopsies be performed when possible.

Abstract
Intramuscular myxomas are benign and rare tumors that affects predominantly the lower limbs. The association of myxomas and fibrous dysplasia, usually polyostotic, is rarer. This association is known as Mazabraud's syndrome, of which about 81 cases have been described in the literature. We present a new case of this uncommon association to emphasise the importance of recognizing this syndrome in the diagnosis and appropriate management of the patient.

Abstract
Myxomas are account for approximately half of primary cardiac tumors, 75% of which originate in the left atrium. We report a case of a right atrial myxoma complicated with bilateral pulmonary embolism. A 54-year-old woman was admitted to the hospital with a complaint of dyspnea. Echocardiography and computed tomography angiography showed a right atrial tumor and bilateral pulmonary embolism. We performed an emergency surgery to remove both the right atrial tumor and the pulmonary emboli. Histopathologically, the tumor was revealed to be myxoma. The postoperative course was uneventful. She is now doing well without any symptoms.

Abstract
A 66-year-old woman who had had coughing and worsening dyspnea for 3 weeks was admitted to our hospital. Echocardiography showed a solid round mass (72×49 mm in diameter) attached to the tricuspid septal annulus with a short stalk. A right atrial myxoma was suspected and operation was performed under cardiopulmonary bypass after heart failure symptoms subsided. The tumor was extirpated along with the tricuspid valve annulus. We performed reconstruction of the tricuspid annulus, tricuspid valve replacement with a bioprosthetic valve and pacemaker implantation. The histopathologic diagnosis was myxoma. The postoperative course was uneventful, and no recurrence has been noted for 1 year after surgery.

Abstract
A 74-year-old man lost consciousness immediately after defecation. The loss of consciousness lasted for several minutes, and he experienced difficulty in walking when he regained consciousness. He was transferred to our hospital via an ambulance. Upon neurological examination, nystagmus and ataxia in the left arm and leg were noted. An MRI of the brain revealed multiple acute infarcts mainly in the bilateral cerebellum. Intravenous thrombolytic therapy with alteplase was initiated 3 h and 20 min after the onset of symptoms, and an improvement in neurological symptoms was observed. Echocardiography displayed a mobile mass in the left atrium, suggesting myxoma. After 14 days from the onset of symptoms, the tumor was surgically resected, and a pathological diagnosis of myxoma was established. Because of the unique event surrounding the onset in this case, we considered that there was a potential detachment of myxoma and/or thrombi fragments triggered by an increase in intrathoracic pressure induced by the action of defecation. This present case suggests that clinicians should consider cardiac myxoma in patients with cerebral infarction if the stroke is preceded by a Valsalva maneuver-like action and accompanied by the loss of consciousness.

Abstract
A 64-year-old man developed right arm weakness and dysarthria, and was admitted to our hospital. Diffusion-weighted magnetic resonance imaging of the brain showed a high intensity area in the frontal lobe. T2*-weighted images showed multiple spotty low intensity lesions in bilateral cerebral hemispheres, mimicking cerebral microbleeds. Cerebral angiography showed multiple aneurysms in the anterior, middle, posterior cerebral arteries and cerebellar arteries. Transthoracic echocardiography revealed a floating structure in the left atrial chamber, indicating cardiac myxoma. We diagnosed cardioembolic ischemic stroke due to left atrial myxoma. Cardiac surgery for excision of a left atrial myxoma was performed on the 3rd hospital day. Multiple aneurysms should be taken into account for differential diagnosis in patients with cardiac myxoma and with atypical spotty low intensity on T2*-weighted images.

Abstract
We report a case of sporadic giant cardiac myxoma with a rare localization in the right atrium, operated in our Service, in a 73-year-old female patient who also presented a patent foramen ovale and a history of ischemic stroke in the year prior to current admission. Intra-operatively, the tumor had a very friable, gelatinous aspect, with a high potential for embolization due to its reduced consistency. The present paper refers to clinical, histochemical and immunohistochemical particularities, as well as to macroscopic and microscopic characteristics of the cardiac myxoma, emphasizing the extracellular matrix aspects, and without leaving out the cellular components of this rare tumor, with possible inference in the management of this disease. The authors present their own observations related to the data from the literature. Also, there are some particularities of the case which justify the current presentation.
